Systematophora varispinosa
Systematophora varispinosa Brenner, 1988
NOW Hysrichosphaerina? Originally Systematophora, subsequently (and now) Hystrichosphaerina?.
Holotype: Brenner, 1988, pl.16, figs.2a-c, prep. N7 II
Stratum typicum: lower Malm gamma, platynota Zone
Locus typicus: Hörnlebruch near Neuffen, Germany
Translation Brenner, 1988: LPP
--------------------------------------------
Brenner 1988, p. 87-88
Occurrence: rare to regular in Malm gamma
Diagnosis: Brenner, 1988, p. 87
A species of Systematophora with varying shape of processes. From the basal ring-like ridges on the precingular and postcingular paraplates 2""", 3""" and 6""" arises one, widened, smooth or perforate process. Additional single, thin processes may be present. On paraplates 4""" and 5""" some thin processes arise from the basal ring which are connected distally by trabeculae.
Descripiton: Systematophora varispinosa differs from other spesies of Systematophora by the extreme variability of the processes and in developing specific process forms for different paraplates of the cysts. The postcingular paraplates 4""" and 5""" consist of numerous, thin processes which are connected distally by ring-trabeculae. These ring-traberculae are usually open towards the paracingulum. Paraplates 1""-6"" and 2""", 3""" and 6""" bear on the part of the basal ring-like ridges opposite the paracingulum a widened, bifid process. The parasulcal plates and the paracingular plates bear one or more thin processes.
